• Briquettes
  • Municipal solid waste and dry agricultural/garden waste can be converted into useful product as an alternate fuel using low cost technology. This waste can be a source of renewable energy when converted into high density fuel briquettes by the process of briquetting.

    Briquetting is the process of converting low bulk density biomass into high density and energy concentrated fuel briquettes.

    Any dry organic waste when completely dried can be carbonized in a kiln. The process involved is burning in the absence of oxygen. The resultant residue after burning the waste in the kiln will be char powder. The carbonization process produces 30% to 45 % char powder from the original biomass. The char powder is mixed with a suitable binder such as starch to enhance charcoal adhesion and to produce identical briquettes using a moulding machine/ hand mould and later drying the briquettes in sun.

    The advantages of using this simple technology is that the briquettes burn without smoke, produces very low ash, high calorific value, odorless and it is a clean and eco friendly fuel.

    Briquetting is one more alternative of handling and using municipal solid waste and also a step forward to keep our environment clean.
